moringaceae, a monogeneric family in capparales (glucosinolate-containing species), includes 14 species. one of them is moringa peregrina (forssk.) fiori., a small tree, which grows in south east of iran. volatile constituents of seed coat and stem of m. peregrina were determined by gc and gc/ms. moreover, extracts of seed and different cultured cells were analyzed by tlc and gc. three volatile...

This study investigated the composition of volatile compounds in two pummelo cultivars, including 'Shatian' and 'Guanxi', cultivated in different regions of China with the aim of studying the effect of cultivar and cultivation condition on biosynthesis of volatile compounds in pummelo. Volatile compounds were extracted from pummelo juice using head-space microextraction and then analyzed using ...

Abstract This paper demonstrates the value of studying co-occurrence ‘quads’ – constellations four non-adjacent lemmas that consistently co-occur across spans up to 100 tokens for understanding discursive change. We map meaning onto quads as ‘discursive concepts’, which encompass encyclopaedic semantics, pragmatics, and context. investigate a high-frequency quad with high strength in EEBO-TCP: ...

The volatile constituents of the aerial parts of vervain (Verbena officinalis L.) cultivated locally were investigated. Analysis of the volatile fraction by GC and GC-MS is described. Compounds were identified by various methods, the major compounds being 3-hexen-1-ol (7.28%), 1-octen-3-ol (32.76%), linalool (4.66%), verbenone (20.49%) and geranial (7.22%).

Analysis of common volatile constituents between herbal pair (HP) Ephedra sinica Stapf (ESS)-Zingiber officinal Rosc (ZOR)and its single herb was performed by the method of GC-MS and alternative moving window factor analysis (AMWFA). Identification of the compounds was also assisted by comparison of temperature-programmed retention indices (PTRIs) on the OV-1 column with authentic samples. AMWF...

Background and objectives: Baneh tree or Pistacia atlantica subsp. kurdica is an endemic plant of Iran which belongs to Anacardiaceae family. It has various traditional uses including astringent and anti-diarrheal as well as improving some of the symptoms of gastrointestinal upsets. In this study we decided to investigate the effects of various fractions of baneh gum ...
